This is a RubyGem that will translate Veewee templates to Packer templates. The conversion is perfect. If 100% of the functionality can't be translated to the Packer template, a warning or error message will be shown, depending on if its critical or not.
Because Veewee is a RubyGem, so too is this converter. Installing using RubyGems:
$ gem install veewee-to-packer
Usage is simple:
$ veewee-to-packer original-template.rb
